Fluidstack; Austin (TX); On-site; USD 224,000 - 344,000; Full time

Job summary

Fluidstack is building a world-class Security & Corp IT team to protect a frontier AI compute buildout. You will own detection engineering, develop telemetry pipelines, and lead high-severity incident responses for a fast-moving, high-scale environment.

You will implement detection-as-code pipelines, drive automation in Python, and collaborate with cross-functional teams to improve security posture and response effectiveness at scale.

Qualifications

• 8+ years in security operations, detection engineering, or incident response at high-growth tech or cloud-scale infra.
• Built or scaled a detection engineering function with defined program, pipeline, and coverage.
• Deep hands-on experience writing detections against cloud telemetry and endpoint telemetry.
• Strong scripting and automation in Python to build detection‑as‑code pipelines.
• Experience leading incident response at scale, with impactful postmortems.

Responsibilities

• Build the detection engineering function from the ground up: telemetry pipelines, detection content, alert routing, and response runbooks.
• Own detection-as-code end to end, with tests, version control, and CI so detections ship reliably.
• Lead incident response for high-severity events, driving containment and root-cause analyses.
• Drive automation of triage and enrichment in Python to scale alert volume without headcount growth.
• Partner with leadership on security strategy, translating threat landscape into a roadmap with clear tradeoffs.
• Collaborate across corp IT and infrastructure teams to obtain telemetry and implement fixes.
